Which ocean is the deepest?
- Atlantic Ocean
- Pacific Ocean
- Indian Ocean
- Antarctic Ocean
The Pacific Ocean is the deepest ocean in the world, with an average depth of 14,020 ft. Other than being the deepest ocean overall in the world, the Pacific Ocean has the deepest point in the world. The deepest point on the planet, found in the Mariana Trench, is nearly 35,797 ft. It is also the largest ocean by surface area. It covers a total surface area of approximately 63,800,000 square miles, translating to a total of 46% of the earth’s water surfaces. The area is larger than all of earth’s land combined. The name Pacific was coined from the Portuguese word “Pacifico,” which means peaceful. It was named “Mar Pacifico” by Ferdinand Magellan because during his circumnavigation trip in 1521 he found the ocean to be very peaceful.

What is the biggest desert in the United States?
- Okanagan Desert
- Mojave Desert
- Great Basin Desert
- Sonoran Desert
Encompassing the better part of 200,000 square miles, the Great Basin Desert is the largest desert in the United States and the second-largest in North America after the Chihuahuan. This ecological realm covers most, but not all, of the physiographic realm of the Great Basin itself, the biggest component of the Basin-and-Range Province. The Great Basin Desert is a cold desert: both a descriptive and formal term. It’s the northernmost major desert province in North America (again, non-polar) and gets most of its scanty annual precipitation in the form of winter snowfall.

Which of America's Great Lakes is the shallowest?
- Lake Ontario
- Lake Huron
- Lake Superior
- Lake Erie
Lake Erie is the shallowest of the Great Lakes and acts more like a river than a lake. Its average depth is just 62 feet. In contrast, Lake Superior has more than 30 times the water volume of Lake Erie, and its average depth is 483 feet. The deepest place on Lake Superior is 1,333 feet, this is six times the deepest point on Lake Erie (210 feet).

What is the deepest river in the United States?
- Yukon River
- Mississippi River
- Colorado River
- Hudson River
The deepest river in the U.S. is the Hudson River which reaches a maximum depth of 216 ft. Some sources also list this depth at 202 ft. Although many people guess that the Mississippi River is the deepest, the river only reaches 200 ft deep as it winds its way through New Orleans. Arguably one of the most significant rivers in the United States, the Hudson River flows for only 315 miles, so it’s not one of the longest rivers in the United States.

Where is the world's largest glacier?
- Asia
- Antarctica

- North America
The largest glacier in the world, Antarctica's Lambert Glacier, is one of the world’s fastest-moving ice streams (ice streams are parts of an ice sheet that move faster than the sheet as a whole). Glaciers like Lambert Glacier and other ice streams are sometimes nicknamed "rivers of ice" because—just like rivers—they flow from places of high elevation to low elevation.
